Nature of problem:
Numerical propagation of classical two-dimensional single and many-body systems, possibly in a magnetic field, and calculation of relevant quantities such as Poincaré sections, survival probabilities, diffusion co-efficients, etc.
Symplectic numerical integration of Hamilton's equations of motion in Cartesian coordinates, or solution of Newton's equations of motion if in a magnetic field. The program implements several well-established algorithms.
Pointlike particles with equal masses and charges, although the latter restrictions are easy to lift.
Program is efficient, extremely modular and easy to extend, and allows arbitrary particle-particle interactions.
The source code is also available at https://bitbucket.org/solanpaa/bill2d. See README for locations of user guide, developer manual, and API docs.
From milliseconds to days, depends on type of simulation.
